In Germany July 12, 1933 3 Claims (01. 221-78) This invention relates to a device for discharging pasty, viscous or liquid substances.

' Hitherto it has been customary to discharge pasty, viscous or liquid substances in predetermined or adjustable quantities from tubular containers composed of tin, aluminium or some other suitable flexible or compressible metal, the container being provided with a nozzle for the discharge of the contents thereof, and with a cap acting as a stopper. These containers or tubes are discarded when empty but they are too expensive, in relation to the value of the contents,

to be so discarded, andthe purpose of the present invention, therefore, is to reduce the cost of such tubes or containers to a very marked extent.

This is, according to the present invention,

rapidly and without much trouble, aflixed to any cartridge or container. This arrangement makes it possible for the manufacturer to supply only I the cartridge or tube proper, and for the distributor or retailer only to stock these comparatively inexpensive cartridges, while on the other hand the purchaser or user requires only once to buy the part provided with the discharge nozzle and designed as the head of the cartridge, and has on future occasions to buy the cartridges only, which are composed of an extremely cheap material, and can consequently be thrown away when they are empty without any appreciable loss.

These cartridges may be constructed either as collapsible tubes or as rigid sleeves. It ispossible to use, for instance, paper coated witha fibre free cellulose acetate film as a suitable maj terial for the said cartridges, or they'may have the cellulose acetate or the like applied to) them in the form of a coat of paint, or an insertion of a metallic foilmay be used, thus making the same cartridges moisture-proof and grease-proof. In order that the said invention may be clearly understood and readily carried into eifect, the

same will now be described more fully, by way of example, with reference to the accompanying drawing, in which:-

Figure 4 is an inverted plan view of the tube.

Figure 5 is a sectional view, and Figure 6 is a cross section, showing the cartridge in the form 5 of a sleeve.

Figure 7 is a front view of a stand or support for sleeve shaped cartridges.

Figures 8 and 9 are views, one in section and the other in elevation, of the upper tube parts; 10 in another embodiment, one open and one closed, an

Figure 10 is a cross section thereof.

Referring to the drawing, there is provided a cylindricalcartridge a adapted to, accommodate 15 the pasty mass or fluid and equipped with a head b (Figure -1) serving for the discharge of the contents in regulatable quantities. The cartridge a may be in the form of a collapsible tube (Figures 2-4) or it may be designed as a solid or rigid 20 sleeve adapted to withstand severe handling (Figures 5-7).

The cartridge is made of extremely cheap material such as, for instance, paper, which has been rendered water-proof and grease-proof by means 25 of an application either on one or both of its surfaces, or by painting it on either one or both of its surfaces, with a coat or film c of fibreless acetate cellulose (Figure 3) or by means of inserting a suitable metal foil (I (Figure 5) between 30 two layers of paper. Should it be desired, other substances may be used having the same properties. It is an essential condition that the ma terial used for the cartridges should be collapsible and adapted to be pressed together when empty- 35. ing the tubes and folded over in a manner known per se. I

'Ihe cartridges a are, after having been filled, adapted to be closed at their upper extremities by means, for instance, of a cork stopper e. These 40 cartridges a are'in principle designed with certain predetermined external diameters, so that the head b canbe aflixed on any of the cartridges In regard to the embodiment shown in Figures 1-f7, the head b 45 is mounted on the extremity of the cartridge a as a lid or cover, whereas it is screwed into the cork stopper 6 in the embodiment shown in Figures 8-10.

b is provided at its bottom side with a projection ff having a through passage or channel 9 provided in it, which latter opens or leads into the discharge orifice h of the nozzle i. A cap is can be mounted on the nozzle in such a manner as to be partially rotatable relatively thereto.

The said internal projection f is also provided 1 with a screw' thread, and terminates in a cutting edge l which serves the purpose of perforating the cover m serving to shut ofi the passageof the stopper e of the finished cartridges, as the head b is being fixed on the cartridge a.

In the embodiment shown in Figures 8-1Q the head b consists only of the projectionj and the nozzle 2'. In this case, the discharge orifice h is provided on the side and is shut ofl by the yieldable material of which the cork e is composed, when the head b is screwed home sufficiently. It the contents of the cartridge are to be discharged, the-head b is unscrewed until the discharge orifice is uncovered.

When the cartridges a are used as"collapsible tubes, they are pressed together at their lower extremities and foldedover, the folded over extremity being retained thus folded, by means of a clamp, which may, for instance, consist of v a suitablepliable metal; at both ends of the said clamp lugs o are provided which are bent around the folded over part of the tube, thus securely holding the various folded over layers,togeth er.

In the rigid constructional form of the cartridges a shown in Figures 5-7, their contents are forced out by means of a piston p which is drawn through the cartridges from the lower extremity upwards. This piston' 1) serves with the rigid cartridges a at the beginning as a, closing device. The said piston is, in the construetional form shown, drawn or pulled inwards, by means of an external handle q -the spindle r of which is in as close proximity to the nozzle i as possible, and extends transversely through the cartridge a, being preferably rotatably mounted and passing through the top cork stopper e ofure 7, be mounted in a suitable stand.

the said cartridge. A catgut "string 3 orjthe like Q is fixed to the said spindle 1', said string being. connected to the piston p and wound on the spindle r of the handle e, thus permitting the piston p to be moved relatively tothe cartridge, a (Figure 5). k

When the cartridge is of the rigid type, it can be used alone, or may, as shown in Fig The said stand may consist or a rigid outer sleeve t provided with a base u into which the cartridge a is introduced from the top. An incisio'n or notch 21 is provided for the neckof the handlerlq, the said notch being preferably'ofo an angular shape, or provided witha lateral rest or stop to, so as to prevent any inadvertent removal' of the cartridge 'a from the tube t.

What I claim is:

'1. A device for dispensing fluent substances comprising a tubular container of substantially f'no value when empty, a plug in oneend of said container traversed bya passage, apiston in the gageable withthe. plug end of the container, and

a nozzle tube on said head adapted to puncture the seal and to'enter the passage whenthe head is applied to the container.

2. A device according to claim 1, in which the means includes a spindle having a handle and a string secured at one end'to the piston andthe other end around the spindle.

3. A device according to claim 1,--in which the means includes a spindle havinga handle and a string secured at one end to the piston and the other end around the spindle, and in which a stand is provided for the container as a rigid outer sleeve having a notchtherein in which the spindle is provided to prevent inadvertent removal of the container from the stand.
